Yes. I didn't do much with wordpress for years, but always thought of it as a very open-source-ish community. Recently I find myself taking on a pre-existing wordpress site with a lot of plugins. I was quite surprised by the way so many plugins are available for $$$. It's sort of impressive "professionalisation" of the ecosystem. I can see it's allowing/encouraging glossy presentation, explanatory videos, documentation, and support guarantes, but there's a voice in my head thinking "Nah! These PHP snippets are all supposed to be free aren't they?"
